According to financial site WalletHub, on average, Americans spend nearly $2,000 a year on energy bills. To find otu which states are the most and least energy-efficient, WalletHub measured the efficiency of car- and home-energy consumption in 48 U.S. states (due to data limitations, Alaska and Hawaii were excluded).

WalletHub calculated home energy efficiency by calculating the ratio between the total residential energy consumption and annual degree days. Car energy efficiency was calculated by dividing the annual vehicle miles driven by gallons of gasoline consumed.

"Each dimension was weighted proportionally to reflect national consumption patterns.
In order to obtain the final ranking, we attributed a score between 0 and 100 to correspond with the value of each dimension. We then calculated the weighted sum of the scores and used the overall score to rank the states. Together, the points attributed to the two major categories add up to 100 points."
